Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a torque machine, particularly a gate valve assembly torque machine. Background Technology

[0002] Gate valves are a common type of valve, widely used in industrial pipeline systems, water supply and drainage systems and other fields. The valve body and valve cover need to be tightly connected to prevent media leakage. A torque wrench can be used to precisely control the torque of the tightening screws to ensure that the connection reaches the specified tightness.

[0003] A search revealed that the utility model with authorization announcement number CN217620397U, entitled "Automatic Tightening Device for Gate Valve Body and Gate Valve Cover," includes a support base, an upper and lower drive mechanism, and a tightening mechanism. Research and analysis revealed that although it can reduce the labor intensity of workers during use, it also has the following drawbacks to a certain extent.

[0004] For example, it does not have a synchronous tightening function. When producing gate valves, the valve cover and valve stem need to be tightened. Traditional torque machines cannot operate the two synchronously at the same time, which means they must be processed separately. Workers need to move the gate valves between different workstations, reposition them and adjust the equipment, which seriously affects production efficiency, prolongs the production cycle, and may also introduce errors due to multiple operations, affecting the overall assembly quality of the gate valve. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a gate valve assembly torque machine with synchronous tightening function, which can simultaneously tighten and fix the valve stem when assembling the valve cover, thus greatly improving processing efficiency.

[0006] The objective of this utility model can be achieved through the following technical solution: A gate valve assembly torque machine includes a top plate and a bottom plate. A first motor mount is bolted to the top of the top plate. A drive motor is bolted to the top of the first motor mount. The output end of the drive motor passes through the first motor mount and is connected to a lead screw via a coupling. The bottom end of the lead screw passes through the top plate and is movably connected to the top of the bottom plate via a bearing. A movable plate is threaded onto the surface of the lead screw. A cylinder is bolted to the rear side of the top of the movable plate. The output end of the cylinder passes through the movable plate and is bolted to a frame. A second motor mount is bolted to the front right side of the top of the frame. A first servo motor is bolted to the top of the second motor mount. A third motor mount is bolted to the front left side of the top of the movable plate. The top of the third motor mount... A second servo motor is bolted to the first servo motor. The output end of the first servo motor is connected to a first drive rod via a coupling. A first drive sleeve is movably fitted onto the surface of the first drive rod via a bearing.

[0009] In the aforementioned gate valve assembly torque machine, a baffle is bolted to the front of the frame, two gears mesh with each other, and the bottom ends of both the first and second drive sleeves penetrate the frame. The surface of the fixed cylinder is movably connected to the frame via bearings. In practical applications, by setting the baffle, the front of the frame can be shielded, preventing workers from contacting the gears and thus improving production safety.

[0010] In the aforementioned gate valve assembly torque machine, a first guide rod is fixedly connected to the bottom edge of the top plate. The bottom end of the first guide rod penetrates the movable plate and is riveted to the top of the bottom plate. In practical applications, by setting the first guide rod, the movable plate can be guided, making its up-and-down movement more stable.
